I do not believe the two witnesses are people but are in fact symbols of the church.

Rev 11.3: The church has been given authority to preach (prophesy) and clothed in sacklocth indicates that sorrow and repentance for sin (cf Mt 28.18-20; Mt 5.4)

Rev 11.4: The two witnesses are described as olive trees and lampstands. this I think indicates peace and illumination. The church is a peaceful society and as the light of the world (Mt 5.9, 14-16; Rev 1) is there to provide illumination thought the preaching of the word

Rev 11.5: The church is indestructable and we can see the end of all who would want to destroy the church (Mt 15.16; Song 6.4)

Rev 11.7-10: Satan is the enemy of the church and this manifests itself in human rebellion. Laws and social trends are all adopted by humanity to limit and restrict and even destroy the church. (Although Ps 2 relates a conspiracy against the Lords anointed, there is that same hatred of the true church) It also pictures the mood of the non-Christian when they perceive the church to be "dead" that is ineffective and irrelevent.

Rev 11.11: A great revival to look forward to. This shows the origin of true revival (cf Ezek 37)

Like most passages in Revelation interpreting it is fraught with problems but this is my basic understanding and based on the principle of scripture interpreting scripture.
